CAKE-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 269,535, dated December26, 1882,

I Application filedAngnst11,1880. (Model) To all whom it may concern:

Be it known that I, WALTER S. OVENS, a citizen of the United States,residing in the city of Bufialo, in the county of Erie and State of NewYork, have invented certain new and useful Improvements in(Jake-Machines, of which the following is a specification.

Cakes such as my invention is adapted for making have heretofore beenmade by means ofa canvas or rubber-cloth bag held and worked by thehands of the operator, the bag being provided with a small opening atthe bottom.

Into this bag a sufficient quantity of the soft cake material is placed,the opening at the bottom being kept closed by the hand until it isrequired to drop some of the materialto form a cake, when the hand isopened slightly, and the necessary quantity drops onto the tray; or, ifit does not flow fast enough, a slight? pressure from the hand forces itout. The bag is now quickly moved up, and if required theopening in thebag is closed by the hand. This operation drops and separates asufficient quantity to form a cake, and is repeated until the tray isfilled.

The object of my invention is to produce a machine for making such cakesmore rapidly, more uniformly, and more cheaply thap can be made by hand;and itconsists ofa cake-machine provided with the usual endless apron,and a suitable means for giving it an intermittent movement, incombination with a verticallyreciprocating dough-box provided with theusual follower, and mechanism for forcing the dough or cake materialthrough one or more openings in the bottom of the box. The object inmaking the dough-box movable vertica-lly is that it may deposit aportion of the cake material upon the tray from each opening during itsdownward movement, and separate the same from the bottom at some pointduring its upward movement, as will be more clearly hereinafter shown.

My invention further consists in the combination, with the dough-box ofa cake-machine, of one or more sliding plates arranged at the bottom ofthe same, and operated by suitable mechanism, as will be more clearlyhereinafter described, for the purpose ofopening and closing the openingat the bottom of the dough-box at the propertimes during the operationof the machine, and cutting off the dough when it is too thick to beseparated by the motion of the box alone, all of which will be moreclearly understood by reference to the drawings, in which-- Figure l isa side elevation of the machine, showing the mechanism for giving thedoughbox a reciprocating movement up and down, also-a portion of themachinery for imparting an adjustable reciprocating movement to thedough-box plunger. Fig. 2 represents a side elevation, showing theoppositeside ot'the machine. Fig. 3 is a plan or top view of the machine. Fig. 4 is an enlarged side elevation of one end of the dough-boxand a portion of said box. Fig. 5 represents an enlarged cross-sectionthrough the dough-box and follower,- also a view ofone of the cams formoving the valves or sliding plates for cutting off the dough. Fig. 6 isa section through the dough-box plunger and screw-column, and through aportion of the dough-box; and Fig. 7 is adiagram on a small scalerepresenting a modification of my invention, showing a suitable meansfor giving the tray a vertical movement instead of the dough-box, bywhich the same result may be obtained, but perhaps not so conveniently.

A represents the frame of the machine. It is made of cast-iron, and heldtogetherin the usual way, and is provided with the vertical sides, A,having the slideways A B represents the endless apron. It is connectedto the frame by the usual rollers, B B (see Fig. 1,) and receives itsmovements by means of a cam, G, on the crank-shaft C, (see Fig. 2,) andan arm, (J pivoted to the frame by a pin or bolt, D, so as to swingeasily. To the arm 0 is connected in the ordinary way a friction-roller,D,.and an arm,

E, having its opposite end connected in the usual way by a pin oradjusting-bolt, E, to an arm, D which is arranged to vibrate easilystepforward tat the upper side) for each rev0- lution of the crank-shaft.Thelength of each movement of the apron is adjusted by moving the arm'Eand bolt E and fastening them in any one of the holes E in the arm D andin the usual way. as will be readily understood by reference to Fig. 2.The tightness of said apron on the rollers B B is regulated in theordinary manner by the thumb screws D The grooved portion 0 of the cam 0gives the reverse movement. to the arm D and its connectingparts.

G represents the fly-wheel, G the drivingpulley, and G the loose pulley.

H is the dough-box. It is provided with a vertical piece, H, at eachend, having boxes H for the shaft I, and projections 1'1 which fit intothe slideways A so as to keep the dough-box and its connections in lineduring its vertical movements.

J in Fig. 1 represents the connecting-rod, having an opening, J throughwhich the plates J are introduced into the bottom of the dough-box, saidplates J being provided with a series ofholes through which the dough isforced when the machine is in operation, and they are constructed in theordinary way. J represents the connecting-rod on the opposite side ofthe machine. (See Fig. 2.) Both connecting-rods are connected by a pin,K, to the crank on the shaft 0, and the upper ends are connected to thedough-box by a pin, K. By this arrangement it will be seen that byturning the crank-shaft U by means of the driving-pulley G and gearing KL the dougl'ibox will receive a vertical reciprocating movement.

L represents the dough-box follower. It is provided with one or two ofthe usual columns, M, screw M, and bevel-gearing M M for the purpose ofmoving the follower up or down into the dough-box. The gear-wheel M isplaced on the shalt l and the wheel M 011 the screw M. The screw is keptup in place by a box, N, made in two pieces and held together by a bolt,N, the head f of the screw being fitted between them so as to turneasily, as shown in Fig. 6. It will now be seen that the screwM will beturned by turning the shaft I, and consequently the gearing M M To oneend of the shaft I (see Fig. l) is rigidly fastened a ratchet-wheel, 0,and between'the frame and the wheel 0 is a plate, d, also fitted to theshaft I, but loosely, so as to be easily turned thereon. It is providedwith a curved slot 6, into and through which a setscrew, g, passes, andscrews into the part H of the dough-box. The object of the screw 9 is tofasten the plate d at any point desired within the limits of the slot 0.At the top of the plate cl is a curved rim, h, which projects outward,so as to cover the teeth on the upper part of the ratchet-wheel c.

i is an angular pawl-arm, fitted loosely on the outer end of the shaftI, outside of the ratchetwheel 0, so as to turn easily back and forth onsaid shaft. It is provided with apawl,j, at

one end to engage with the teeth of the wheel 0, and an arm or rod, 1,pivoted at the otherendxi, the lower end of which rod 2 passes loo elythrough a stud, m, and is provided with stops, at n. It will be now seenby reference to Figs. 1 and 3 that as the dough-box moves downward, therod 1 moves with it, moving through the stud at until about onehalf ofthe down stroke of the dough-box has been made, when rod l, andconsequently as the dough-box continues its down movement the angulararm 2' is turned, carrying the pawl j with it and turningtheratchet-wheel one step forward,which operation turns the shaft I, thebevel-wheels M M and the screw M, therebyforcing the plunger L. a slightdistance downward for every down movement of the dough-box.

The object of the plate (I, with its curved slot 6 and curved rim hprojecting over the teeth ofthe ratchet-wheel, is to render themovements of the ratchct-wheel adjustable. It will be noticed that therim It extends around the top of the wheel about the length of thestroke of the angular arm t', and that the pawlj in its backwardmovement slips over the top of said rim h more or less, according to theadjustment of the rim. Ifitshould be adjusted within one tooth of thewhole movement of the pawl forward, then the ratchet-wheel will move onetooth ahead for each forward movement of the pawl. 1f adjusted withinthree or four teeth of its full movement, then said wheel will be movedthree or four teeth forward for every forward movement of the pawl.

0 represents a slotted cam for operating the cut-off slides l of thedough-box by the up-aud-down movement of said box. There are four ofsaid cams, two on each side of the frame. (See Figs 1, 3, and 5.) Theyare bolted to the frame by bolts 1%, which passthrough slots It, so asto be adjustable vertically. The shut-off slides P are provided on eachside with a frictionroller, Q, which fits into and works in the slots 0of the cams 0. (See Fig. 5.) As thedough-box moves up and down theslidesP are held in place by the parts S S which act as slideways for them. Itis obvious that a downward movement of the dough-box will cause theslides P to open, and that an upward movement will cause them to shutand cut off the dough.

The operation of the machine is as follows: The dough-box being filledwith dough and at the limit of its upward movement, as shown in Figs. 1and 2, and the cam 0 being moved in the direction of the arrow 2, saidcam moves the endless apron 13 one step forward on the upper side.During this time the dough-box descends to about one-sixth (more orless) of its downward movement when the friction-rollers Q. which areconnected with the slides P and move down with the dough-box, reach theinclined portion of the cam-slots O, and as the dough-box continues itsdescent for about one or two six'ths of its downward movement, it willbe readily seen that the slides P will be the stop it prevents thefurther descent of the opened. After the dough-box has descended toabout the point last mentioned the stop n on the rod or arm I hasdescended far enough to come in contact with the lug m, which preventsthe further descent of the rod 1, and consequent] y the remainingdownward movement of the dough-box causes the arm t and pawlj to turnthe ratchet-wheel c, and through the gearing heretofore mentioned itforces the follower L down into the dough-box a sufficient distance toforce out dough enough to drop the required number of cakes on the tray.During the upward movement of the dough-box the dough is either brokenoft'during such movement or is cut oft' by the slides P being shut, ashereinbetore mentioned. As the machine continues the operationis'repeated.

' limit of its upward movement in said figure.

Of course it will be readily seen and understood that all the movementsof the cams and gearing for operating the dough-box follower can begiven just as well by the vertical movement of the apron as by thedough-box, and that the cam C will move the arms E and D and th rebygive the endless apron its proper forward movements equally as well asit would if it did not have a vertical movement, there being in thatcase only a little ditt'erence in the length of the feed, which could beeasily provided for by changing either the throw'of the cam O orthelength of the arm D to allow for the difference, if necessary. Anotherequivalent way of giving the endless apron and tray a vertical movementwould be to connect the apron-frame by cranks or eccentrics at each end,and gear the crank-wheels together by, chains or other suitable means,so as to move simultaneously. In some cases when the dough have theusual continuous movement insteadof an intermitting movement, ashereinbefore mentioned, and, if desired, the dough-box may be moved bymeans of ca ms instead of cranks and connecting-rods, as described.

I claim as my invention 1. In a cake-machine,.an intermittingly-movingendless apron for carrying the tray along as the cakes are depositedthereon, in combination with a vertically-movable dough-box providedwith a follower, L and a. suitable mechanism, substantially asspecified, for giving it the necessary movementsr 2. In a cake-machine,the combination of a movable dough-box with the cams 0 and cutoff slidesP, for the purpose of cutting off the dough during each movement of thedoughbox, as herein set forth.

3. In a cake-machine, a movable dough-box provided with-a shaft, I, andgearing ill M, in combinatioirwith a ratchet-wheel and paw], a stud, m,and arm l, having stops nu, for giving the required intermittingmovements to the follower, substantially as described.

4. In a cake-machine, the combination, with a material box, of apan-supporting table, and mechanism for vertically moving one toward andaway from the other, whereby when the machine is in operation thematerial flows from the nozzle upon the pan, and when the deposit ismade the connection between .the deposit and the box breaks,substantially as set forth.

5. A movable dough-box provided with one or more slides, P, incombination with one or more cams, 0, made adjustable, as and for thepurposes described.
